I have only got half way through this thread but I like the idea of a quiz. Honestly it would have to be a test / quiz that would get you to think vs a test with right or wrong answers. I guess anything that keeps the "plan" or a plan anyway, on the forefront of your brain then it has accomplished what it set out to do. It made you learn, think and question. I like to critically think out things, however, after a while you get VERY fast at going through a scenerio. I like the idea.
